John Baldwin pointed me at it wondering why I hadn't answered, and that's why :-). Is the number of mbufs lost proportional to total run time since the start, or number of runs since start? I.e., if you shorten 60 seconds to 6 seconds but sample at the same rate, what impact does that have on the measured leakage?
